Abstract
The invention relates to a motor, in particular to a single-bearing fully-enclosed self-ventilated motor, and aims at solving the problem that insulation aging of a motor is accelerated since the existing self-ventilated motor is complicated in structure, large in occupied space and complicated in assembly and fine particles may easily enter the inside of a motor body to cause a fault. According to the scheme, an enclosed air duct is formed in the lateral walls of a suspended end cover, a driving end support end cover and a stator assembly; an air inlet is formed in the suspended end cover; an air outlet is formed in the support end cover; the suspended end cover, the stator assembly and the support end cover are in stopping fit; a cylindrical roller bearing is supported on the suspended end cover; a rotor assembly is supported on the cylindrical roller bearing; a centrifugal suction fan is arranged at a non-driving end of the rotor assembly; and a seal plate is arranged in the driving end support end cover. The single-bearing fully-enclosed self-ventilated motor has the advantages that (1) a cavity of the motor is enclosed, dust filtration is not needed, the structure is simple and the space is reduced; (2) the design is simple and reasonable, the assembly process is simplified and the cost is reduced; and (3) the air duct and the cavity of the motor are independent, so that insulation aging and a ground fault are avoided.
Description
Technical field
The present invention relates to a kind of motor, be specially the totally-enclosed self-ventilated machine of single-bearing.
Background technology
At present, installation is easy to operate, be easily maintained and overhaul, be subject to the favor of motor user without draught fan matching, the advantage such as lightweight with it for self-ventilated machine, and therefore, self-ventilated machine obtains the commonly used of machine field.Existing self-ventilated machine adopts traditional duplex bearing supporting construction mostly, and its air channel is open relative to motor cavity, and namely air channel connects with motor internal cavity, its can meet must degree of protection requirement, such as IP23 degree of protection；Owing to traditional duplex bearing self-ventilated machine parts are more, assembly technology is complicated；Its open air channel structure requires that its air inlet arranges dust filtration device, takes up room relatively big, assembling complexity；Cooling air enters motor, and its fine particle contained can be piled up at motor internal, there is the hidden danger of initiating failure, and electrical machine insulation has certain damage, accelerate the aging of electrical machine insulation.Therefore, it is necessary for designing the totally-enclosed self-ventilated machine of a kind of single-bearing.
Summary of the invention
This invention address that existing self-ventilated machine structure is complicated, it is big to take up room, assembling is complicated, fine particle easily enters internal body initiating failure, accelerate the problem that electrical machine insulation is aging, it is provided that a kind of totally-enclosed self-ventilated machine of single-bearing.
The present invention is achieved by the following technical solutions: the totally-enclosed self-ventilated machine of single-bearing, suspends end cap, motor stator assembling, rotor assembling, bearing, fan, seal disc, driving end supports end cap in midair including motor；Described motor suspention end cap, the sidewall of driving end supports end cap and motor stator assembling is provided with the air channel closed relative to motor cavity, the air inlet in described air channel is arranged on motor hanging end lid, air outlet is arranged in driving end supports end cap, described motor suspention end cap, motor stator assembles, it is connected for seam between driving end supports end cap, motor hanging end lid supports and has cylinder roller bearing, the assembling of described rotor is supported on cylinder roller bearing, the non-transmision end of described rotor assembling is provided with centrifugal induced draught fan, arrange in described driving end supports end cap and seal disc is installed.Air channel is arranged at the sidewall of suspention end cap, supports end cap and stator assembling, and close relative to motor cavity, between end cap with stator, seam coordinates, motor cavity is completely enclosed, air channel by the end cap of motor, stator assembling sidewall and cavity in carry out heat exchange, it is to avoid fine particle enters motor internal.Motor suspention end cap inherits the suspended fixing seat of motor, supports cylinder roller bearing on it simultaneously, it is simple to installs and safeguards.The non-transmision end of rotor assembling arranges centrifugal induced draught fan, cooling air is sucked by the air inlet on the hanging end lid of non-transmision end, flow through the closing air flue on suspention end cap, stator assembling sidewall, by carrying out heat exchange in sidewall and machine cavity, then derived by the air outlet in driving end supports end cap, it is achieved under the totally-enclosed condition of machine cavity, cool down the purpose of motor.Seal disc in driving end supports end cap, and be arranged between the motor side shaft coupling cylindrical that rotor assembling power transmission shaft is stretched when motor is installed and used and stay certain interval, it is possible to play and prevent foreign body from being entered the effect of motor internal by gear-box.The motor of the present invention, when installing and using, the driving end of motor is closely cooperated by the gear-box of driving end supports end cap Yu vehicle, play the effect supporting and positioning, the driving end axle of the rotor assembling of single-ended support stretches to connect and is connected with gear-box shaft coupling, transmission moment of torsion, thus realizing the single-ended support of rotor assembling.
The invention have the advantages that 1, by improving Duct design, it is achieved the closing of machine cavity, it is not necessary to dust filtration device is set, simplify electric machine structure, saved space；2, structural design is more simple, reasonable, simplifies motor packaging technology, has saved manufacturing cost；3, air channel and machine cavity are independent, it is to avoid cooling air enters insulation ag(e)ing and the earth fault that machine cavity causes.
